Mini-review on the phyto-chemistry, pharmacology and toxicology of <i>Cola nitida</i> (Vent.) Schott & Endl. (Malvaceae): A medically interesting bio-resource of multiple purposes in Africa

Abstract

The purpose of this mini-review was to summarize and update knowledge on the phytochemistry, pharmacology, and toxicity of &lt;i&gt;Cola nitida&lt;/i&gt;, with the view of providing baseline data for herbal drug formulation. In January 2021, a non-exhaustive online search of relevant articles was carried out on the phytochemistry, pharmacology, and toxicology of &lt;i&gt;C. nitida&lt;/i&gt; from scientifically well-established databases such as Science Direct, PubMed, Web of Science, Scopus, Google Scholar, and SciELO. The plant's scientific name as well as phytochemistry, pharmacology, pharmacognosy, bioactivity and toxicology were used as keywords. The chemical structures of the compounds isolated from this plant were drawn using ChemBioDraw Ultra 12.0 software. A literature survey has revealed that &lt;i&gt;C. nitida&lt;/i&gt; is highly appreciated by African populations in various cultures, especially in West Africa. Phytochemical analyses showed that &lt;i&gt;C. nitida&lt;/i&gt; contains interesting compounds like catechin, caffeine, epicatechin, polyphenols, alkaloids, tannins, saponins, bromelain, cardenolides, proanthocyanidins, triterpenes, glycosides, flavonoids, anthraquinones, steroids, anthocyanins, glycosides, alkaloids, etc. The presence of these phyto-compounds in the investigated plant species justifies its used as an antimicrobial, anti-malarial, anti-inflammatory, anti-diabetic, anti-coagulant agent. Thus, &lt;i&gt;C. nitida&lt;/i&gt; could be used as a raw material for manufacturing efficient medication against various diseases, including sickle cell disease.
